"How to find shortcuts to adiabaticity - Brachistochrone problem in quantum systems"
Kazutaka Takahashi (Tokyo Institute of Technology)
The method "shortcuts to adiabaticity" (STA) is known as a one accelerating the adiabatic dynamics of quantum systems and has now been under intensive study. We show that the STA can be derived from the quantum brachistochrone equation, which allows us to establish how fast and robust the obtained trajectory is. We also discuss possible deformations of the counterdiabatic Hamiltonian. They can be useful for complicated systems such as many-body ones and are important for practical applications.
